Bug ID: 60940
Summary: general operations on atomic t ypes do not work with
atomic integral typedefs
Product: gcc
Version: 4.10.0
Status: UNCONFIRMED
Keywords: rejects-valid
Severity: normal
Priority: P3
Component: libstdc++
Assignee: unassigned at gcc dot gnu.org
Reporter: redi at gcc dot gnu.org
This is rejected because the atomic operations only accept std::atomic<T> not
the std::__atomic_base<T> base classes:
#ifdef __cplusplus
#include <atomic>
using namespace std;
#else
#include <stdatomic.h>
#endif
atomic_int i;
int main()
{
atomic_store(&i, 0);
return atomic_load(&i);
}

--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
Additionally, we fail to meet this requirement:
29.6.2 Templated operations on atomic types [atomics.types.operations.templ]
The implementation shall declare but not define the function templates
identified as “templated operations on atomic types” in 29.2.
We only declare those functions templates when they need to be defined, i.e.
for arguments of type __atomic_base or atomic<T*>.
The declarations would need to be constrained with SFINAE to prevent them being
used for types derived from __atomic_base.

template<int... I>
void dummy( const A< I... >& );
int main()
